Principle
WINDRYOur Screw Vacuum Pump is a masterpiece of engineering, featuring dual paralleled screw rotors with a meticulously crafted pump body that forms multiple sealed spaces. The precision-engineered rotors and pump body maintain minute clearances, ensuring no contact and frictionless operation. Driven by reverse gears, gas is seamlessly transferred from the inlet to the outlet, guaranteeing superior, uninterrupted performance.
The frictionless design of the dual rotors and pump body eliminates the need for lubrication, delivering clean and pure gas. The continuous gas transfer, combined with a streamlined pathway, maximizes efficiency. The innovative placement of the outlet below the screw rotors enhances drainage capability and simplifies cleaning. With the absence of an intermediate bulkhead, our design surpasses claw and rotor vacuum pumps in both drainage and exhaust efficiency, making it remarkably easy to maintain.
